Update (i.e., retraction time): We just received a note from the Evolutionary Media Group confirming that this is indeed a private event, as the Good Doctor asserted below. The confusion stems from an ambiguously worded press release we received this morning from EMG that lead us to believe this event was open to the public (mainly because it didn't clearly say otherwise). Our apologies for the misinformation. Please disregard the testimony below, unless, of course, you're among the fortunate VIPs who have been "pre-allocated" tickets. The good news here is you can catch Silversun on the esurance main stage at Monolith on Saturday, September 13.

Just learned of an event titled Unconventional ’08 that will feature a slew of indie rock acts such as the Silversun Pickups, Cold War Kids, Nada Surf, Clap Your Hands Say Yeah!, as well as a performance by DJ Z-Trip on Wednesday, August 27.

Presented by Manifest Hope and San Francisco mayor Gavin Newsome, the event is being produced in tandem with an exhibition of renown visual artists including Shepard Faire, Sam Flores and Ron English, among others, whose work will be showcased alongside five winning artists from an online contest overseen by MoveOn.org. Tickets for the show, which will be be held on an outdoor stage near Andenken Gallery on 29th and Larimer, can be obtained by stopping by Andenken. There's also reportedly another gig that night featuring Ben Gibbard (Death Cab for Cutie), Jenny Lewis (Rilo Kiley), Zooey Deschanel (She and Him), Matthew Caws (Nada Surf) and Jonathan Rice, but that show is reportedly an invite only VIP event. -- Dave Herrera
